Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Luckily, you’ve got a thing that sends out energy at small chips（芯片） in everyone’s name tag（标签）.The chips send back name, job, hobbies－whatever. Making new friends becomes simple.

This hasn’t quite happened in real life. But the world is already experiencing a new age of using RFID technology.

An RFID tag with a small chip can be fixed in a product, under your pet’s skin（皮肤）, even under your own skin. Some RFID tags have no energy source because they do not need it. The energy comes from a scanning device（扫描装置）, which sends out energy and starts up the tag immediately.

Such a tag carries information to that object, and the information can be renewed. Already, RFID technology is used for recognizing（识别） each car or truck on the road and it might appear in your passport. Doctors may put a small chip under the skin to get a patient’s medical records. At a nightclub in Paris or in New York the same chip might get you to pay for the bill with the wave of an arm.

Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The idea was that computer chips could be put everywhere and send information in a smart network that would make life simpler.

RFID tags are a small part of this situation. “The world is going to be a connected set of personal small devices.” predicts Dr. J. Reich. But some people are nervous about the possibilities of such technology. It goes too far tracking（跟踪）school kids through RFID tags, they say.

When Marconi invented radio, he thought it would be used for ship-to-shore communication, not for pop music. Who knows how RFID and other technologies will be used in the future. Here’s a wild guess: Not for buying milk.

1.The article is intended to______.

A. warn people of the possible risks in adopting RFID technology

A. will have no trouble getting data about others

B. will have more energy for conversation

C. will have more time to make friends

D. won’t feel shy at parties any longer

3.Passive RFID tags chiefly consist of____.

A. scanning devices B. radio waves

C. batteries D. chips

4.Why are some people worried about RFID technology?

A. Because children will be tracked by strangers.

B. Because market competition will become fiercer.

C. Because their private lives will be greatly affected.

D. Because customers will be forced to buy more products.
